SAFETY ATTACHMENT FOR OUTBOARD MOTORS Filed March 27. 1948 INVENTORWALTER A. WARDIUIS ATTORNEYS Patented Apr. 15, 1952 Y 'UNITED STATESPATENT OFFICE SAFETY ATTACHMENT' IFOR UUTBOARD MOTORS .1 Claim.

ing provided with a lock-strap, having an eyed A head engaging the motorhinging bolt, that is housed infthe standard enginepintle sleeve.

.A further Object of my invention is to provide the flower `end of thelock-strap with a slot, for engagement .with and permanently pivotedtothe clip-plate.

A further objectof my invention is to provide a key control lock, forthe button to prevent theftof .the engine.

`With the Vabove and other objects Vin view, which will appear as thedescription proceeds, the invention resides in the novel construction,combination and arrangement of parts, substantially as hereinafterdescribed, and more particularly defined by the appended claim, it beingunderstood that such changes in the precise embodiment of the hereindisclosed invention may be made as come within the scope of the claim.

In the accompanying drawings is illustrated one complete example of thephysical embodiment of the present invention constructed according tothe best mode so far devised for the practical application of theprinciples thereof.

In the drawings:

Figure 1 represents a side elevation of an outboard motor, embodying thefeatures of my invention, the same being shown attached to the sterngunwale of a boat.

Figure 2 is an enlarged fragmentary, sectional elevation of the saine,the section being indicated by line 2--2 of Figure 3.

Figure 3 `is a front face view of the same, being a section asillustrated by line 3--3 of Figure 2.

Figure 4 is a detailed cross-section as indicated by line 4--4 of Figure3.

Figure 5 is another detailed sectional view through the lock-strap andassociated parts, the same being indicated by line 5--5 of Figure 3.

Figure 6 is a longitudinal sectional View, through the lock-strap andassociated parts, the section being indicated by line 6--5 of Figure 3;and

Figure 'l is a similar sectional View illustrating 2 the lock-strap andassociated parts shifted to their :unlocked position.

Referring by characters to the drawing, Aindicatesa motor housing, ofthe Evinrude type, thefsame fbeing `attached to the stern gunwale, B, ofa boat, :by a stern bracket 1I, which bracket is provided with the usualspaced .legs l.

The :motor housing has projecting therefrom a neck, `which neckterminates with `a Ahinge 'sleeve 2, seated between the flegs .I of therstern bracket I.

The hinge `sleeve 2, vis .pivotally mounted hetween the `bracket legsbyaboltt, Whichbolt engages suita'ble Vapertured lugs of :the bracketlegs Il.

All of the :above-.mentioned elements form no part :ci my invention, andthe standard 'stern bracket is seated over aclipplate 4, :which.clipplate '-is `provided `with countersunk apertured recesses :rior`retaining screws 5, 'as vbest indicated in -Fi'gure 4 of the drawings.The screws 5 are shielded by discs S, `which discs are carried byclamping bolts '5, in threaded connection ywith he lower ends of thebracket legs I', whereby the motor is firmly clamped to the sterngunwale.

My safety attachment comprises a lock-strap 8, having an eyed head 8',which head is nested within the pintle sleeve 2, in engagement with thebolt 3.

In assembling, the lock-strap, the head 8 thereof, is introduced intothe sleeve 2, through an aperture 2 and thereafter the bolt 3 isproperly assembled. The lock-strap 8 is secured to the bolt 3, by aset-screw 9 that is in threaded connection with the eyed head 8' andsaid setscrew frictionally secures the head to the pivot bolt 3.

It should be understood that in assembling the lock-strap and bolt, thesaid strap is swung outwardly from left to right, whereby access may behad to the set-screw through the sleeve aperture 2.

By this arrangement, when the lock-strap is in its normal position, theset-screw 9 is inaccessible.

The lower end oi' the lock-strap 8 is provided with a longitudinal slotI0 for the reception of a button Il, which button is pivotally mountedupon the screw I2. In order to provide this screw i2 as a permanentconnection with the button i i, the said button is formed with acountersink, for the reception of a fluid metal cap |21', which capcannot be removed. l

It will be noted that the slot l0 of the strap engages a projecting bed4', whereby the strap is held against play in any direction.

As best shown in Figure 6 of the drawing, when the lock-strap isfastened to the clip-plate 4, the button I I is swung downwardly wherebythe said strap is held in its secured, normal position.

In this normal position it will be noted that the motor may be usedfreely by authorized persons, but should it be desired to lock the motoragainst theft, as indicated by dotted lines Figure 3 of the drawings,any standard lock C, may be inserted through a hole II of the button,whereby it would be impossible to shift said button for the purpose ofdisconnecting the strap from the plate 4. As noted in Figure 7 of thedrawings, when the lock C is absent, the button vcan readily be swungupon its pivot in alignment with the bed 4', whereby the strap, asindicated in dotted lines may be swung free from the clip-plate. Y

As best illustrated in Figure 6 of the drawings, the clip-plate 4 isalso secured by a wood screw positioned below the locking button I I.VThus when the lock-strap is in position the securing screw 5 is coveredby the end of said strap, whereby the same is inaccessible.

From the foregoing description it is apparent that an unauthorizedvperson cannot remove the motor from the gunwale ofa. boat, keeping invmind that all of the disconnecting elements are protected, and forexample it would be impossible to remove the pintle bolt 3 from itshinge sleeve, due to the fact that said bolt is positively connected tothe strap head by the set screw 9.

While I have illustrated my safety attachment associated with a specifictype of out-board motor, it should =be understood that said safetydevice is applicable to al1 types of motors, the only mechanical changebeingthat the eyed head 8 of the lock-strap, may be laterally extendedto meet certain conditions of the other types of motors.

I claim:

A device for locking outboard motors against accidental loss andunauthorized removal from boats of the type wherein the boat is providedwith a permanently attached clip-plate, and the motor is rockablymounted upon a hinge bolt carried by a boat engaging bracket, saiddevice comprising a strap secured to the hinge bolt for swingingmovement therewith and depending therefrom over the clip-plate, anoutwardly projecting rigid Ibed formed on the clip-plate below the hingebolt and bracket, said strap having a longitudinally extending slottherein adjacent to its outer end receiving the rigid bed when the strapis swung down over the clip-plate, and an apertured button pivoted tosaid bed movable into and out of alignment with the bed and the slot ofthe strap to selectively conne or release the locking strap.
